THE VERDICT

The Sea to Summit Talus TS II is a lightweight, comfortable mummy bag that performed well in a variety of conditions and climates. But the bag could be warmer with more down and the temperature rating is ambiguous.

FULL REVIEW

CompressibilityThe Talus II fits very easily into its compression stuff sack and compressed to the smallest size of any bags in this category. This small size provided me with several options when storing the bag in my backpack.

WarmthThe 750 plus loft down made this bag hold body heat well, which resulted in a warm bag in temperatures in the the high 20s. Any lower than that and I was forced to add clothing to sleep comfortably. In temperatures in the lower 20’s and high teens, I began to feel a bit of draft via the zipper area and was forced to add more layers of clothing.

FeaturesThe Talus TS II uses offset baffles, a side block baffle to keep the down from migrating and also to help with warmth. These baffles were successful in temperatures into the high 20’s. The tapered foot bed was comfortable and allowed me to rest with my size 13 feet facing upward very comfortably.

The Talus II comes with an internal zipper pocket that is suitable for a phone, headlamp, music source or any other small item that may be desirable for easy access and to keep close to the body for extended battery life. I do wish the pocket was a bit bigger for greater storage options.

The Talus TS II comes in both a regular and long size and with a left and right side zipper. The Talus TS II comes with a water repellent nylon 2D NanoShellTM which repelled tent condensation well. The Talus II also comes with an anti-snag zipper that did not snag once during the testing phase.

Sea to Summit features what they call an integrated sleep system, which provides sleeping bags, sleeping pads, sleeping pad accessories, and pillows. Unlike their competitors that offer sleep systems, Sea to Summit does not use straps to attach the sleeping pad to the sleeping bag, but merely a line of sleeping bag and pad accessories that work together. The Talus TS II uses ULTRA-DRY Down™ which is treated to repel moisture, improve loft and dry faster and therefore improve the down’s performance.

Overall ComfortThe Talus TS II provides good loft and a subtle and soft inner liner that felt comfortable and cozy when I cinched the bag around me. The Talus TS II provides enough room inside the bag that I could move around easily, but not so roomy that I could not stay warm.

DurabilityThe Talus TS II showed no signs of wear during the testing phase. While the shell feels light-weight, it repelled condensation, dirt and debris well.
